EnergySource 4:1 tested in Cycling Weekly Magazine.

EnergySource 4:1 was tested in the Feb 25 2006 issue alongside a number of leading energy drink companies. The verdict was:

" Measuring the powder is simple with the provided scoop and there are also excellent guidelines for dosage according to the athlete's bodyweight. The taste is good a little chalky, which is likely down to the protein - containing ingredient. Other than that, this is a great drink, and well worth trying."
